TELICE, A CONTRACTOR FOR ELECTRIFICATION, SIGNALLING AND RAILWAY COMMUNICATIONS SYSTEMS, IS CURRENTLY DEVELOPING THE EVOLUTION OF THE WORKSTATION FOR THE AUSCULTATION OF CATENARY TCAT®, MAKING USE OF LIDAR TECHNOLOGY FOR THE CALCULATION OF GEOMETRIC PARAMETERS OF CATENARY AND RAILWAY.
tCat® project
The tCat workstation has been developed to facilitate and speed up the monitoring of catenary parameters: contact wire height and offset, track width and cant, and other parameters for catenary design and maintenance.
The tCat is an easily operable device characterized in the European Norms as a “light weight track geometry measuring device” (LTGMD) which can be adapted to the three common track gauges (1,000,1435 and 1680mm).
Its main components are:
An inertial measurement unit (IMU) with 6 degrees of freedom and integrates an accelerometer and a gyroscope both of three axes.
A global navigation satellite system (GNSS).
A differential transformer linear variation (Linear Variable Differential Transformer LVDT) used to calculate the track axis.
A digital camera.
An odometer (rotary encoder) with high precision.
A LIDAR system (Laser Imaging Detection and Ranging), that allows a great speed and precision in the measurements.
A new battery will guarantee the autonomous operation of the equipment for at least 8 hours
Closure
TELICE once again demonstrates its innovative spirit by creating a commercial product which, even in its development phase, stands out for its ease of use, speed and precision.
